DRILLlNG GLASSWARE.

Patented Aug. 21, 1906.

Application filed July 25, 1905- Sarial No. 271,245.

To all whom it may concern:

-'Be it known that I, JOSEPH G. MARTIN, a resident of Fostoria, in thecount of Seneca and State of Ohio, have invente a new and usefulImprovement in Machines for Drilling .-Glassware;-'and I do herebydeclare the fol lowin to be a, full, clear, and exact descrip- I tion tereof.

a 'plan .view of my machine, one of t e dle-bearingsbeing broken away.Fi 2 is a,

:with vertical be more arms 4, whic My invention relates to adrilling-machinal and more especially to a multiple-spindle machinefor'drilling hollow glassware and similar' articles. i

The object of the invention is to improve machines of this character indetails of ar-. ra ement and construction hereinafter descri ed. a z

In the accompanying drawings, Fi re is spincentral vertical section.Fig. 3 is a si e view,

' on an enlarged scale of a portion of the frame and one of thespindle-bearings and Fi 4 is a longitudinal section of one of the chucs;

- My machine will'be rovided with any suitable base, such as s own at 1,carryin the standard or frame 2, which is provided arinfis 3 and withthree or project radially outwardly and upwardly. These arms at theirring 15 are all formed of a single upper ends are provided withhorizontal 'faces 5, upon which rest bearing members 6 for the drill-sindles 7. As many bearing members 6 wi be provided as there are slpiilli- 'dles in the machine, the particular mac illustrated having sixradially-arranged spindles. The bearin members 6 have twobearing-sections 8 an 9 united by side members or bars 10. The severalbearing members are connected by means of the braces 1 1 which "areshown as cast integral withthebearing "members; This, however, is notnecessary, as they may be formed of suitably secured together. At theirinner ends the bearing members are provided with tr 'sverse openings .12for receiving the beveled' pinions 13 on the drill-spindles '7. At

theirextreme inner ends these bearing members are provided'with arms 14,which project inwardly and downwardlyf and are connected to a rin 15 forreceiving a suitable s shown in the drawings, the 11, arms 14, and

bearing members 6, braces integral separate pieces I handle foroperating the same.

casting; but obviously they may be formed of separate pieces, ifdesired.

- The drill-spindles 7 are held in the bearing members by means of caps16 and 17, the latter being provided with a hood 18 for covering u thebeveled pinion 13. The several bevele pinions 13 are engaged by atoothed rim or crown-gear 20, provided with spokes or arms 21, curvindownwardly and connecting the toothed nm with the hub 22. The latter issuitably secured to the upper end of a hollow shaft 23, mounted in thebearings 3 in the base-frame 2. This shaft is provided with a beveledgear 24, which engages a similar gear 25 on a driving-shaft 26, mountedin a bearin formed in one side of the frame 2. The sha t 26 may bedriven by an suitable means or in any suitable Way. spindles will be fedtoward the work yield.

ingly., For this purpose I- provide spiral.

springs 28, surrounding the drill-spindles and bearing at their outerend against washers 29, seated against the outer bearing members 8 andat their inner ends bearingagainst col-- he drillcollar 32 is providedwith a downwardly-pro jecting lug or .pin 34, which extends into a slot35, formed in the arms 4 or bearing members 6, as the case may be, so astoprevent saidcollar from turning with the s indle.

The machine-frame is provided wit only three arms 4. Consequently everyalternate bearing member 6 will have a slot 35, formed in the bottomconnecting member 36, as indicated on the right-hand side of Fig. 2.

The several ins 34 project through camslots 38, forme in a ring 39,suitably mounted'on the arms 4 and in the bearin members 6. This ring atone side is provi ed with a The several cam-slots 38 project on anangle, as shown in Fig. '1,- so that when the ring is turned all ofthespindles will be simultaneously withdrawn. At their outer ends the(cam-slots are provided with straight ortions 42,- so thatwhen thespindles have l ieen fully withdrawn they will be held in that position,the pins 34 then resting in the portions. 42 of'the slots. In order tofeed the spindles forward, the ring is rotated slightly, so as to causethe pins to clear the straight portion 42 of the cam-slots and come intothe inclined portions thereof. The springs 28 will then continue to feedthe spindles inwardly. One of the braces 11 is provided with a depressedportion 43, as indicated in Fig. 1, to makeroon'i for the handle 40.-

The work-holder is so constructed as to hold the work yieldingly. It isshown as a sleeve 45, suitably secured in the ring 15 .by means ofcollars or nuts 46 and provided with a cushioning-lining 47, which maybe formed of cork, rubber, or other suitable cushioning material. Thehollow lass article is shown at 48 as projecting own into thework-holder while t e drills are operating thereupon.

In drilling glassware and the like it is nec: essary to supply water tothe part being drilled. For this purpose I supp y suitable 4 water-pi es50 for directing a jet of water against t e article at each drill. Inorder to permit this water to drain away, Isecure to the inner endofflthe bearing-members 6 a suitable basin or cup 51, provided in itsbottom with an opening 52, which communicates v with the opening 53 inthe hollow shaft 23, so

that the water and grit will be conducted away from the machine.

The drill itself is shown at 54. It is comprised of a suitable body ofabrading material. It may be held in any suitable chuck secured to the,inner ends of the spindles 7,

that shown comprising asplit sleeve 55, having an external'taperedthreaded face for recelving an integral tapered nut 56. Any other chuckwill answer the purpose equally aswell. g

The articles to be drilled are inserted in the machine from above andall of the operating mechanism is underneath, so "as to give easy accessfor the insertion and removal of the articles. Provision is made fordraining .away the water and grit, so that the latter cannot get intothe bearings or gears. In fact, all of the gearing is well housed andprotected' from the water and grit.

The 0 eration of the machine will be understoo from Y the foregoindescription; Themachine as a whole is simp e of construction, contains aminimum number of parts, and provides forfeeding the drills yieldinglyas well as holding the article yieldingly, so. f

that breakage is reduced to a minimum.

Various changes may be made in the form and'location of the severalparts without departing from the spirit of my invention. a
